[0021] Furthermore, a first handle 2 is fixedly connected to the lower end of the outer wall of the caulking rod 1, and a first caulking brush 3 is fixedly connected to the upper end of the outer wall of the caulking rod 1, and the outer wall surface of the first caulking brush 3 is set as an arc-shaped corner, and a second caulking brush 11 is fixedly connected to the upper end of the outer wall of the movable rod 5, and the outer wall edge of the second caulking brush 11 is set as a sharp corner, and the outer wall surface of the second caulking brush 11 fits well with the inner wall surface of the first caulking brush 3. This structure can be used by switching the first caulking brush 3 and the second caulking brush 11 to scrape different positions of the ceiling, and the first caulking brush 3 can avoid partial damage to the ceiling when caulking.
[0022] Furthermore, a rubber ring 4 is fixedly connected to the lower end of the outer wall of the first handle 2, a second handle 9 is fixedly connected to the lower end of the outer wall of the movable rod 5, and a limiting ring 10 is fixedly connected to the outer wall end of the second handle 9. The inner wall of the rubber ring 4 is adapted to the outer wall of the second handle 9. This structure can enable the second caulking brush 11 to be used for a long time through the adaptation of the rubber ring 4 and the limiting ring 10 when the second caulking brush 11 is used.
[0023] Furthermore, the adjustment component includes a slot 6, a slot 6 is opened on the lower side of the inside of the caulking rod 1, and a right spring 7 is arranged in a fit on the inner wall surface of the slot 6, the middle of the inner wall of the spring 7 is adapted to the outer wall surface of the movable rod 5, a block 8 is fixedly connected to the lower side of the outer wall of the movable rod 5, and the outer wall of the block 8 is in a fit with the inner wall of the slot 6, and the upper end of the outer wall of the block 8 is abutted against the lower end of the outer wall of the slot 6. This structure can interchange the use of the first caulking brush 3 and the second caulking brush 11, so that they can be used in different positions facing the ceiling.
[0024] Furthermore, a screw rod 12 is fixedly connected to the upper side of the outer wall of the movable rod 5, and the outer wall surface of the screw rod 12 is connected to a limiting nut 13 through a threaded connection. The outer wall end of the screw rod 12 is inserted into the inner lower side of the baffle 14, and the inner opposite surfaces of the two sets of limiting nuts 13 are fitted with the outer wall of the baffle 14. A guide groove 15 adapted to the outer wall surface of the screw rod 12 is provided on the upper side of the outer wall of the caulking rod 1.
